MY build and all the benchmark numbers

[Woomack]

Interesting find this morning. In a MSI bios there are two separate locations to access PBO...one in Settings and the other in the OC tab. The problem with that is one will override the other...they don't speak to one another despite the format/settings being identical. It was a real head scratcher why my bios changes were not showing up in tests until I figured this out.

I barely used any AM5/MSI mobo, but I assume this is the same as on every other AMD mobo brand. Each mobo manufacturer has its own OC tab, and there is also a "standard" AMD OC tab. Both have most of the same settings, but not all. Those who buy a cheaper mobo that lacks manufacturer's options can still find some OC options in the AMD OC tab.
I noticed that on some brands, not everything works, or some options override others. On the other hand, the list is long, but most options are useless.

Indeed it is. There's typically TWO ways to access that. Never playing with it, I THOUGHT that they would be in sync with each other, not one working and one not, lol. That's odd to me.

As suspected, it looks like your temp limit is putting a glass ceiling on performance (~3% from 75-95C) with these settings. I also suspect once you put the negative offset back on the scores will be closer.

It makes sense there isn't a change in gaming as the temps likely aren't reaching these levels/where it 'throttles' in the first place... that or it doesn't need the extra 3% it's getting. Did you test COD at 1080p(cpu bound) or 4k(gpu-bound)?

PBO is set to Advanced, motherboard, + 200Mhz and - 20 both CCD's. I use a 1440p monitor so I did not test any other resolutions. You can see the increments in the Cinebench scores at each thermal limit. Verifies the absence of any gains/losses in games, but then again I'm only looking at FPS numbers and thermals.

-20............mv?

1440p uses less CPU than 1080p, so that jives.

On ASRock, some options are missing in the main tab, but others work the same in both tabs. On ASUS the same, but PBO works better in the main/ASUS tab. On earlier Gigabyte I didn't want to play with standard options as the mobos were acting weird, like not everything was working. The latest Gigabyte seems fine, but because I know it's useless, I didn't really try much except for some RAM options. On Biostar is another story, as nothing works as expected everywhere
It also depends on the model and BIOS version.

That monitor curve + distorted pic........ I get vertigo just looking at them, LOLOL!

Short answer is, yes, that is for voltage (I had to look it up, lol).

Why do you change voltage here, and adaptive? Why not just use this to reduce voltage?

Not certain I understand your question. Are you asking about the vcore? I have done next to nothing yet on this dual CCD cpu when it comes to the Curve Optimizer or Curve Shaper.

 

[EarthDog]

Not certain I understand your question. Are you asking about the vcore?

Yes.

That's what that setting does is lower your Vcore. Then, I think it was you (this thread is mess, lol), you change the adaptive voltage too?

 

[67Elco]

Yes.

That's what that setting does is lower your Vcore. Then, I think it was you (this thread is mess, lol), you change the adaptive voltage too?

I think you are limited as to how much you can do in the optimizer...like if I tried -30 it might not boot. Setting the vcore voltage manually seemed more predictable to me and it still adapts...just limited to my exact specification. I would have to run each and watch it in HWINFO to compare. At any rate, my vcore voltage is now set to auto. I still need to test the effects of CCD vs all core vs per core on this cpu to see what works best.

 

[EarthDog]

Is it not as granular? You increments are 10/20/30 etc? Increments of 10, versus when using adaptative you can set it to whatever?

First off PLS someone tell me what the FCLK does to ram and is it important?
I also downclock my ram when trying to OC the CPU so those dont affect each other.
Since im running all 4K settings can that explain the 200 point decrease compared to Elco?
And now you guys are seeing the issues im running into with CPU OC settings as no two motherboards have the same settings or also act different with similiter settings.
Plus i swear no two people OC the same way. Ive seen 4 setting OC's that were a mess and 20 setting OC's that just locked my pc up tight.
depending on how you word it my ram ive kept stock settings with or downclocked it manually, I run no OC on it even day to day.

First off PLS someone tell me what the FCLK does to ram and is it important?

This is what google tells me...

FCLK, or Fabric Clock, refers to the clock frequency of the Infinity Fabric interconnect on AMD Ryzen processors. It's a clock signal that synchronizes data transfer between the CPU cores, memory, and other components on the chip. Essentially, it governs the communication speed between the CPU's different parts.

Zen 5 and Beyond:
With newer Zen 5 and later architectures, the recommended approach is often to leave FCLK on AUTO, allowing the BIOS to manage it based on the memory controller and DRAM, according to TechPowerUp.

...if you're benching at Hwbot, sure, mess with it. Otherwise, leave it alone.

I also downclock my ram when trying to OC the CPU so those dont affect each other.

depending on how you word it my ram ive kept stock settings with or downclocked it manually, I run no OC on it even day to day.

Just let it run JEDEC. That means, no EXPO... no downclocking, nothing. Load Optimized Defaults from the BIOS (F10? F7? I dont recall). Slow as slow can be.... THEN work on the CPU OC. When you get the CPU OC, set it back to stock (load optimized defaults in the BIOS), THEN OC your RAM. As far as wording, you ARE overclocking the IMC as it's rated to DDR5-6000 (anything over DDR5-6000 is overclocking the IMC). You are NOT overclocking the RAM as it's rated for 6400 MHz.

And now you guys are seeing the issues im running into with CPU OC settings as no two motherboards have the same settings or also act different with similiter settings.

No two CPUs have the same settings. Each CPU is different. This can be confusing, you're not wrong. But I also think you're making it more complicated in several ways.

Plus i swear no two people OC the same way. Ive seen 4 setting OC's that were a mess and 20 setting OC's that just locked my pc up tight.

Again, no two CPUs are the same so what you see on YT vids, may have to be tweaked for your own system.

Since im running all 4K settings can that explain the 200 point decrease compared to Elco?

It's a CPU test. Testing your brakes tells you nothing about the Air Conditioning, for example.

Excellent post Earthdog.
Ok ill knock it back to jedec specs and leave on auto.
So as said before "Learn your bios" will be my biggest help.
Once i wake up ill try and watch a few videos and see if they lead me anywhere.

 

[67Elco]

Just beginning...the all core setting has the lead over CCD at the moment...

Im gonna go back and retry the setting you showed me with the 4 screen shots, Im not gonna do it immediatly so if you want to change something tell me.
ATM my goal is stock voltage or lower and a 200Mhz OC on the core and on the turbo together.

Don't copy the numbers on my screens. Stumble around until you find Precision Boost Overdrive and do this -

Precision Boost Overdrive - Advanced

PBO Limits - Motherboard

Precision Boost Overdrive Scalar - x10

CPU Boost Clock Override - Positive

Max CPU Boost Clock Override - 200 (This is all it will allow)

Platform Thermal Throttle Control - Auto

Leave everything else alone, F10 to save settings and exit. Test the difference. If all is well the next time you enter bios save your current settings in a profile and name it something you recognize...like PBO-1. Every time you make a change in bios do this so in case of a failure to boot or a crash all you have to do is load that profile instead of jumping all around the bios trying to remember what settings you had last that were stable. Take a screenshot of those bios settings if you think of it. Once you get this foundation set you can then move on to Curve Optimizer and/or Curve Shaper.

will do man, I found i have a "search" box in my bios so i shouldnt have issues finding the right setting to tweak.
Later when i get this down a bit i want to undervolt if its possible but thats another step past this.

 

[freeagent]

You don't need to touch the scalar. I would avoid.

Once you find PBO everything related should be right there. Undervolting is a rabbit hole...don't go there any time soon.
